ECX-53B SMD Quartz Crystals

ECS ECX-53B SMD Quartz Crystals feature a low-profile 3.2mm x 5mm footprint. These miniature SMD crystals have a frequency range of 8MHz to 50MHz with up to ±50ppm frequency tolerance. The ECX-53BQ series meets AEC-Q200 qualifications and has an extended temperature range option. The ECX-53B series is suitable for compact wireless applications where board space is critical, while ECX-53B-DU crystals are ideal for communication and test equipment.
